The need to deliver high performant and miniaturised electrochemical sensors has boosted the use of carbon nanomaterials as smart modifiers of working electrode surface. Among the carbon nanomaterials, the common and cost-effective carbon black has recently attracted the attention from the scientific community for its outstanding features as electrode nanomodifier for analyte detection. Herein, we report the structural and morphological characterisation of several types of carbon blacks, namely HP 160, HS20, MTN 990, N115, N220, N375, N660, PL6, Super P, and XE2B, by means of Raman spectroscopy, transmission electron microscopy (TEM) and scanning electron microscopy (SEM) analyses. Furthermore, the electrochemical characterisation of screen-printed electrodes modified with these carbon blacks was carried out by cyclic voltammetry and electrochemical impedance spectroscopy with ferro/ferricyanide as redox probe, highlighting the advantage to use carbon black as nanomodifier in respect to the bare electrode. Among several tested carbon black types, the lowest peak-to-peak separation and resistance to electron transfer values were achieved using screen-printed electrodes modified with CB N115, N375, HP 160 and PL6. The electrodes modified with these types of CB were successively tested in cyclic voltammetry towards epinephrine, benzoquinone, ascorbic acid, cysteine, catechol, and caffeic acid, observing a remarkable improvement of electrochemical performances in respect to the bare electrode, even when the amperometric mode was used. The results obtained demonstrated that several types of CB can remarkably improve the electrochemical performances of the sensors in terms of the decrease of applied potential or peak-to-peak separation, the improvement of the peak intensity, and the decrease of the resistance of the electron transfer due to several key features, including nanodimensions, the onionlike carbon structure, and the high number of defect sites.

The modification of SPCE with carbon black and AuNPs improves the sensitivity allowing a very low detection limit of 8.8×10–9 M. The combination of MagMIP with SPCE/CB/AuNPs improves significantly both sensitivity and selectivity.The developed analytical procedure was applied successfully to water samples .…”

This review focuses on the recent achievement during period of 2013–2018 related to the electrochemical sensors based on molecularly imprinted polymers (MIPs) combined with nanomaterials for various kinds of applications. MIPs based electrochemical sensors have found a great interest due to their high stability, short time required for electropolymerization, and high specificity towards the target analyte. The sensitivity is considered as one of the important parameter in electrochemical sensing strategies that should be improved by the combination of highly conductive nanomaterials with selective MIPs. In general, the most employed nanomaterials are magnetic nanoparticles, gold nanoparticles (AuNPs), carbon nanotubes and graphene. This review discusses the main current achievement as well as the current challenges regarding the development of biomimetic sensors in electroanalysis.

e demand of energy storage as well as affordable and easy-to-handle healthcare and environmental monitoring systems is increasing with the incessant growth in the world population. erefore, there is a prodigious need for more economic and efficient technologies for energy storage and sensors for healthcare and environmental monitoring application. e advancement of carbon nanostructured materials, dimensions ranging from tens to several hundreds of nm, dating back to the past few years, has seen a tremendous scientific growth in the field of battery and supercapacitor [1], bio, chemical, and mechanical sensors [2][3][4][5][6], and possible related applications as illustrated in Figure 1 [7][8][9][10][11][12][13][14][15]. ese nanostructured carbon materials own unique characteristics, such as superior electrical conductivity, tunable porosity, outstanding mechanical strength, and remarkable thermal, optical, and chemical properties because of their nanosized and very high surface-area-to-volume ratio [16,17]. ese outstanding structural characteristics of carbon nanomaterials help them to interact with other materials for numerous innovative applications, such as in energy storage and conversion and sensing.is special issue is envisioned to provide an insight into the role of nanoscopic features in improving the functional properties of carbon nanomaterials and their composites, such as amorphous and graphitic carbon, carbon nanofibers, nanotubes, and graphene, and composites with metal and metal oxides. In this special issue on carbon nanostructures for energy and sensing applications, we have invited a few papers that address such matters. e first and second papers of this special issue address electro-oxidation of formic acid (FAO).e first paper reported about the CuOx-Pd nanocatalyst supported on a glassy carbon (GC) electrode. A distinct class of nanostructured catalyst made up of binary palladium nanoparticles (PdNPs) and copper oxide nanowires (CuOxNWs) has been realized onto the GC electrode. It was found that the deposition sequence of both nanostructures onto the carbon electrode influenced the catalytic efficiency heavily. e highest catalytic activity and stability were obtained at the GC electrode surface with partially deposited CuOxNWs on CuOx/Pd catalysts. e second paper demonstrates a binary platinum (Pt) nanocatalyst on glassy carbon surfaces with earth abundant iron oxide nanowires (FeOx/Pt) for improved formic acid electro-oxidation, and it was found that nanocatalyst displayed a better (∼4 times) catalytic activity as compared to bare Pt electrode and that when triggering the catalyst at ∼0.5 V, the catalysis enhanced ∼8 times.Carbon nanomaterials, specifically graphene, graphene oxide, nanotubes, and nanofibers owing to their high accessible surface area and porosity, capability of easy surface functionalization and suitability make them to serve as a support material for various types of adsorbents to solve the purpose of desulfurization [18]. e third paper is a comprehensive review on carbon n...
